In fact, it’s pretty common for humanity to revise its views over time. For example, a couple of centuries ago, we knew ‘for sure’ that only birds and angels could fly in the sky, half a thousand years ago the very idea of printing books looked like complete nonsense, and around the same time almost the whole world was damn sure that the Earth was actually flat... hmm, well, not the best example, I agree.

In fact, if you look at the selection of the most popular opinions from the original thread, you can see that almost half of the examples given are somehow related to the Internet. Yes, that’s right - three decades ago, scientists seriously believed that the very opportunity to gain access to all the knowledge of humanity almost directly from your favorite couch, the opportunity to discuss anything with a person on the other side of the globe - this is the path to unprecedented progress in knowledge! And where on [flat] Earth did we take a wrong turn?

However, there is nothing surprising - all sorts of weird ideas and theories have always existed, but if previously their spread was actually hampered by distances between people, as well as the banal factor of time and money, then the Internet erases boundaries not only for knowledge.
Suppose I had some really stupid ideas about a hundred years ago, then, in order to get people interested in it, I have to spend a lot of time and money to write a book, publish it, promote it in bookstores and magazines... Today? It’s enough just to create a topic on Reddit and write a post, isn’t it?

However, no one is immune from the fact that everything that we believe in today, that we are so sure of, will not turn out to be ‘strange nonsense’ a couple of centuries or even decades later. After all, twenty years ago, Pluto was officially listed as a planet...
Okay, I still feel bad for Pluto, but in the meantime, feel free to read this selection to the very end, vote for the submissions you agree with the most, and maybe add your own ideas in the comments below. In the end, as the ancients used to say, ‘truth is born in disputes...’
